Remove old code and dependencies, update tests

Delete the old resolution job replaced by `CollectSubjects`, adapt
its unit tests, and do some cleanup in the new job's mapper. This
renders the JFresnel dependency and FSL paths in resolve.properties
obsolete, so remove these too.

While at it, remove the old main to run the jobs locally (replaced
by the integration tests) and the even older experimental SPARQL
stuff not used anywhere in the project.
